Issuing an executive order is not a new idea. It has been used many times before.

In 1989, then-President George H.W. Bush halted the importation of some semi-automatic firearms that could be considered “assault weapons” under existing legal authority provided by the 1968 Gun Control Act, under the determination that they were not “particularly suitable for or readily adapting to sporting purposes.”

Bush used his executive powers after a career criminal killed five kids and wounded 29 others with an AK-47 assault rifle on Jan. 27, 1989, in California.

4. Bill Clinton AND George H.W. Bush both have issued executive orders regarding gun control

-snip-

There's ample precedent. After a mass school shooting in Stockton, California, in 1989, George H.W. Bush issued an executive order, pursuant to the 1968 Gun Control Act, that banned imports of certain assault weapons unless used for sporting purposes. Years later, Bill Clinton by executive order banned imports of almost five dozen different assault weapons that had been modified to get through that "sporting purposes" exemption. President Obama could go even further.
